Write an explicit formula for the An, and the n^th term of the sequence 24,-12,6,....
Annette [7]

Answer:

T_n =  -48* (-\frac{1}{2})^{n}

Step-by-step explanation:

Given

24, -12, 6,...

Required

Write a formula

The above sequence shows a geometric sequence because:

r = \frac{-12}{24} = \frac{6}{-12} = -\frac{1}{2} -- common ratio

The equation is determined using:

T_n = ar^{n-1}

Where

a = 24

Substitute values for a and r

T_n = 24* (-\frac{1}{2})^{n-1}

Apply law of indices:

T_n = 24* (-\frac{1}{2})^{n} * (-\frac{1}{2})^{-1}

T_n = 24* (-\frac{1}{2})^{n} * 1/(-\frac{1}{2})

T_n = 24* (-\frac{1}{2})^{n} * 1*-2

T_n =  1*-2*24* (-\frac{1}{2})^{n}

T_n =  -48* (-\frac{1}{2})^{n}

<em>The above represents the explicit formula</em>

What is the graph of the function <br> f(x)=−⌊x⌋
kupik [55]

Answer:

Step-by-step explanation:

The equation being shown in the question is the absolute value of x. Absolute values when graphed show up as a V-shaped graph pointing upwards. This is because whatever value is passed as an input will output a positive, regardless of whether the input is positive or negative. Meaning that both 4 and -4 will output 4. That is why the graph is a V-shaped because the outputs repeat for both positive and negative inputs. In this case since the negative is outside the absolute value brackets the positive value given from the absolute value of the input will be turned into a negative. So this will cause the V-shape graph to be reflected across the x-axis. As seen in the attached picture below.
